Abstract
FINDING: Orch-OR theory posits consciousness arises from quantum computations in microtubules, with objective reduction (OR) as a gravitational threshold for wavefunction collapse, but current evidence is indirect and contested. MATH: - OR criterion: \( E_\Delta \approx \hbar / T \) (energy uncertainty × coherence time ~ Planck's constant) — Penrose's gravitational self-energy: \( E_\Delta = \frac{1}{4\pi G} \int ( \nabla \phi_1 - \nabla \phi_2 )^2 \, d^3x \) (difference in gravitational field between superpositioned mass distributions). - Microtubule lattice: tubulin dimers arranged in hexagonal (6-fold) symmetry; quantum coherence proposed at ~10 MHz (vibrational modes), with decoherence time \( T \sim 10^{-13} \) s in warm wet brain — a major mathematical obstacle. - No new equations in the cited videos; the arXiv paper (2105.02314) combines integrated information theory (Φ, a scalar measure) with collapse dynamics (e.g., GRW or CSL), but no specific ratio or constant emerge Author: Andrew Stewart Caldin, Independent Researcher, UK.
